T0 at? whom it may concern:

Be it known that I, JULIUS Pnnnms', a citizen of the United States of America, and residing at Omaha, in thecounty of Doufglas and State of Nebraska, have invented certain new and useful Improve merits in Axle Thrust-Bearings, of which the following is a specification, such as I will enable those skilled in the art to which it appertains to make and use the same.

. This invention relates to axle thrusts, particularly in car journal boxes, and the objectthereof is to take up the said thrust anti-frictionally.

A further object is to make the said stitution or repair.

A further ob ect -1S to provide, in car journal boxes, eliicient-rneanr: for. maintain ing the. thrust devices in operative position, said means not interfering in any Way with the lIiStflllfliilOll or removal of the usual elements in such boxes A still further object is to so construct the said thrust device holding means as to be 4 adaptable to a frictional thrust device if necessary or desirable for any reason. A further object is to make the said thrust device of such dimensions as to prevent its removal when the axle is in position in the box. T

' A further object is to so construct the v holding means, Within the box, as to prevent the lodging of refuse or other matter there in whereby the true seating of the thrust device might be interfered with, thus posi tively insuring a predetermined positioning thereof, this being of the highest importance when an anti-frictional thrust is employed for the reason that the said thrust must be. maintained in constant concentricity with the axle end; and a still further object is to provide such devices Which are simple in construction, highly efliciont in operation, readily installed and removed, and comparatively inexpensive.

My invention is fully set forth, in the following specification, of which the accompanying drawings form a part, in which the separate parts are designated by the same reference characters in each of the views, and in whichi Figure -1 a vertical section taken through a car journal box provided with my axle thrust deviate; Fig, Zis similar view preferably integrally, is an abutment plate '2), adyacent to the axle end a, said plates being vertically arranged and extending but a short distance toward the box center,

and arranged beneath each of the said plates and inwardly thereof is a supporting lug having a downwardly and outwardly inclin'ed upper surface and, in practice, 1 preferto provide strengthening ribs 6 for the plates 1), and it will be observed, by ref erence to Fig. 3, that the lugs 6 do not extend as far beyond the box Wall as the plates I) "for a-reason hereinafter pointed out.

My present preferred forzn'of thrust doe vice, as shown in: Figs. 1, 3 and 4, comprises a block 0 provided with an car 0 on each sidethcreof having inclined. lower surfaces corresponding to the inclined surfaces on the lugs 31 and with which they are adapted to engage, the weight of the said block also holding the same against the plates 6, because of the said incline, but in a readily detachable manner.

The block 0 is recessed on its inner face, as shown at o, to a depth approximately equal to the diameter of a series of balls c arranged therein and, in practice, I prefer to provide a hardened bearing ring 0 for thosaid halls secured in the said block i; any desired manner, and said balls are held in position by means of a disk d having a control depression (l of an external diametcr about squat to the diametrical distance between the bu ls, said disk being held in position by means of a bolt (5 and a nut 03", l or equivalent, permitting its rotation, the under surface of the disk bearing directly on the balls as is clearly shop-in in Fig. i.

In Fig. 2 I have shown an alternate or emergency form of thrust device, comprising merely a block 0 provided also with cars in the manner of the block 0, only one of said ears being indicated, and I may lighten the block e by boring, as shown at 6 this device being frictional Whereas the form hereinbefore described is anti-frictional, the

block 6 being stored in stations, shops, or

the like, for use in case of collisions or other;

accidents wherein the. antiefrictional device is injured or destroyed.

It will thus be seen that' I provide ajreadily detachable axle thrust device, the holding 10 means wherefor do not, in any way, interfere with the normal functions of the box a or contained elements, the normal thrust device being perfectly anti-frictional, and the said.

' holding means are also adaptableto ithe I5 emergency, frictional, thrust device shown, or to any suitable modification thereof; my

anti-frictional thrust device is very simple in construction, perfectly efficient, possesses .great strength, is comparatively inexpensive and, being composed of but few parts,

cannot readily get out of order to require repair, nor do my thrust device holding 'means .add materially to the cost of the box.

The-blocks c and e are made of a diameter nearly as great as the box interior, as shown in Fig. 4, and the lugs b are therefore necessarily shorter than the plates 5, the latter extending inwardly of the block periphery in order to serve as a support therefor, this diameter of the block preventing, because of the height of the incline of the said lugs, from being displaced therefrom through the medium of the box top against which the said block strikes in the jolting of the car 3 when in motion, said block being removable only after the axle has been removed, thus preventing workmen or curious persons from removing the thrust device, which removal might resultin the loss of or injury to the same.

' By reference to Fig. 2 it will be observed that there is a clear space provided between the abutment plates 6 and the lugs 6 permitting refuse or other matter to pass downwardly into the box and thus preventing the lodgment thereof on the said lugs to interfere with the true seating of the cars 0 for it is very essential that the thrust be always maintained in exact relationship with the axle end, particularly when anti-frictional thrust means are employed, these requiring that an absolute concentricity be maintained betweenthe same and the axle end.

While I have shown a preferred method of producing the desired results, it will be evident thatchanges thereover'may suggest themselves and still be within the'scope of my invention and the following claims and, Having fully describedmy invention, what Letters Patent,is:- T I Y 1. In a journal box having an axle therein, an-,axle thrust device arranged in' the .plane oi and closelyadjacent the axle end,

[ I do claim as new and desire to secure by 5 Said.- device comprising a block having ears on the sides ther'df inclined on their lower faces, supporting lugs, in said box, similarly inclined for said ears, and means in said box for limiting the downward and outward movement of-said ears on said lugs, said 1 lugs and limiting means being spacedapart to permit thepassage of refuse'ntherebe tween.

2. In a journal box having anaxle therein, an axle thrust device arranged in the plane of and closely adjacent the axle end, said device comprising a block havingears. hesides thereof, inclined on their lower fa; 'sgisllpporting lugs in said box, similarly inclined, for said ears, andan abutment so plate on each side of said box for limiting the movement of said ears on said lugs, said plates taking the impact of said device in the .axle thrust, said lugs and abutment plates being spaced, apart to permitfthe passage of refuse therebetween.

3. In a journal box having an axle therein, and provided with inclined supporting lugs on either side of the interior thereof, and with abutment plates adjacent thereto and spaced apart therefrom to permit an unobstructed passage for refuse therebetween, an axle thrust device aheld on said lugs'and comprising a block h ing ears on the sides thereof inclined similarly to said lugs and resting thereon, a disk rotatable on said-block, and anti-frictional means interposed between said block and disk.

4. In a journal box haxing an axle therein, and provided with inclined supporting 1100 lugs on either side of the interior thereof, an, axle thrust device comprising a block having ears on the sides thereof'inclined similarly to and resting on said lugs, a disk rotatable on said plate, anti-frictional meaiISf..'10E
